Intel Atom On Ubuntu, Fedora, OpenSuSE, Mandriva

Phoronix: Intel Atom On Ubuntu, Fedora, OpenSuSE, Mandriva

Back in September we looked at the Intel Atom performance on a few Linux distributions using the ASUS Eee PC 901, but now with new stable releases of some of the most popular distributions out in the wild, we've decided to re-conduct these tests. We are using a slightly different Atom-based system this time and we are comparing the performance on Ubuntu 8.10, Fedora 10, Mandriva 2008, and OpenSuSE 11.1.

I am very interested in your benchmarks, but I wanted to know if there is any reason not to display a standard deviation in those graphics. (Maybe to know also how many times you have performed the measures would be interesting too).

As far as I know, only OpenSUSE turns barriers on by default (using ext3). That would explain why it's so much slower in some tests (like the SQLite test), but strangely it makes no difference in IOzone. I guess this could be more a proof of IOzone being a bad benchmark than anything else, since in real world tests barriers do make a big difference when it comes to IO intensive tasks.

More then likely beagle (the indexing service) which is enabled by default is the culprit.

You give the impression that you're a tad biased against Mandriva, by using the 2008 version while 2009 is out :/ And I didn't see Mandriva in the GTKPerf tests, and there wasn't even a mention for it in the final page :/

Architecture?

I don't know if other distributions do that too, but Ubuntu has a special architecture named "lpia" with all the packages rebuilt to take advantages of Atom features. So, did you use Ubuntu lpia or Ubuntu x86 for your tests?
